Chronic exposures and male fertility: the impacts of environment, diet, and drug use on spermatogenesis.

摘要: Several recent studies have suggested that sperm concentrations and semen quality been decreasing over the past several decades in many areas of world. The etiology these decreases is currently unknown. Acute events can significant impacts on spermatogenesis are often readily identified during male fertility evaluation. majority factor infertility, however, idiopathic. Chronic, low-dose exposures to chemicals nutrients more difficult identify, but extremely prevalent. These shown dramatic effects both individual community health interest cumulative synergistic such agents has increasing. While our understanding potential hazards evolving, it clear they may significantly influence reproductive potential. This review explores literature related chronic from drug use, dietary intake, environment humans animals.
